Your question raises as many issues as it clarifies. Why is the grandmother relevant? I taught a course on Friday on the subject of Nevada child custody law, which included the recent cases addressing grandparent involvement, but I cannot tell from your question what, precisely, is in play.
A short course on "relocation" is posted on our child custody page, at http://willicklawgroup.com/child-custody-and-visitation/, and I would suggest that you start there, reviewing the cases and outlines.
So the short version answer to your question is "yes, probably.," but more information -- what orders are now in place, who has said and done what, etc., is necessary for a more detailed answer. A consultation with a family law specialist is strongly advised.
